Nebulae

If we translate the Latin word nebula it would simply mean cloud. In this case the cloud contains nothing more than dust and gas. Some of these clouds are regions of star formation
and others are the result of dead or dying stars. Nebulae (plural) offer some of the most spectacular views in the night sky. There are four main types: planetary, reflection,
emission and absorption (or dark). Examples of all these are shown in the images below.
